GDQUlRr-LQCKING DEVICE.

Application filed January 12, 1922, Serial No. 528,6 l9.

To all whom it may concern Be it known that 1, WILLIAM E. WINE, a.

citizen of the United States of America, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Car-lQ oor-Locking Devices, of which the following is a specification. v

My invention relates to new and useful improvements in car door locks and has for an object to provide a lock comprising a bracket or base plate, which is designed to be secured to the side ofa freight car, and on which bracket is eccentrically mounted a hook which in turn is designed to support a-drop bottom door; first, in a partly open position and, from which point, the hook will be raised to force the door to its final and locked position where it will remain until the hook is manually operated to release the door.

As is well known to those skilled in the art, drop bottom doors are easily handled or manipulated with the exception of the final closing and locking movement, as often times the doors become distorted or warped in service or small particles of coal or other substance jam along the sides or hinged edge of the door and it is necessary to exert great force to raise the door the last few inches.

Another object of the invention, therefore, is to provide a hook which cooperates with a transversely mounted angle on the door to support the door in its nearly closed position, and to have this hook eccentrically mounted so that a wrench may be placed on the eccentric mounting of thehook so that the hook may then be swung beyond the lower pivotal axis which will raise the hook and door and' lock the door in its closed position. I

Still another object of the invention is to provide a locking arrangement consisting of a bracket on which is eccentrically mounted a hook and behind which is mounted a dog toffurther hold the hook in its closed position .so that it will be impossiblefor the hook to open unless the hook is manually manipulated.

Still another object of the invention is to provide a locking means for drop bottom doors which will consist of but few parts, relatively strong, easily operated and relatively cheap to manufacture. v

With these and other objects in view my invention consists in certain new and novel construction and combination of parts as willhereinafter be more fully described and pointed out in detail in the claims.

Referring now to the drawings showing a preferred embodiment of the invention,

Fig. l is a side elevation of the locking device, a fragmentary portion of the side of a car being shown and one edge of a drop bottom door, the door being in its closed and locked position.

Fig. 2 is a similar View, the door in this instance, beingshown in a temporary partly closed position, the lock being swung to its open position.

- Fig. 3 is a detailed sectional view taken on line 3-3 of Fig. 1, and

F 1g. 4 is a sectional view taken on line 4.4 of Fig. 1.

In the drawings a fra entar ortion 1 of the side of a car is slid ivn, al ir cket 2 which is secured to a center sill (not shown) to which bracket is hinged the door 3 and across and beyond which extends an angle iron 4 to provide a supporting ledge on the door 3 which rests on the supporting ledge 5 of a hook 6, while the door is, in its locked position. 7

Referring now, more particularly to the locking device, there will be seen a plate or bracket 7 which is'substantially triangular in shape and is secured by three rivets 8.to the sideof the car 1, a plate 9 being placed behind the bracket and side of the car 1 throu h which are also passed the rivets, the p ate forming a reinforcement so that the bracket and hook will not be torn from its position. v

This base plate or bracket -7 is provided with three integral outstanding bearing posts 10, 11 and 12 which are drilled for the reception of'the aforesaid rivets 8, and on two of which bearing posts are mounted the hook 6 and dog 13 respectively, while the lower bearing post 11 forms a stop for the inward movement of the hook 6. A strap 14 s secured on the outer ends of the two posts 11 and 12 and is held by two of the rivets 8,- which strap prevents transverse movement of the hook t5 and the dog 13.

center thereof. It will be noticed that the hub 17 is slightl reduced as at 19 so that although the hoo 6 may pivot on this hub the flange formed by'the reduced portion 19 will prevent any looseness or transverse movement of the head 15 on the hub 17 It will be seen that when the hub and hook are swung to the position shown in Figs. 1 and 3 the hook will be held in its uppermost and locked position and will remain in this position as the pull will, be to one side of the lower pivotal axis. 'The hub 17 is of suflicient width to provide a bearing surface for a wrench so that the eccentrically mounted hook may be easily swung to its open or closed position.

Supposing the door is open, the dog 13 will have been thrown back to the position shown in Fig. 2 and the door will then be raised by hand to a temporary supporting position as shown in Fig. 2 so that the angle iron will rest on the ledge 5 of the hook 6. The hub 17 may then be grasped by a wrench and revolved to the position shown in Figs. 1 and 3 which will exert great force on the door, pulling it to its uppermost position -and holding the same against "accidental opening, this of course, due to the eccentric mounting of the hooks. After which the dog will be swung over as also shown in Fig. 1 to further provide against any accidental disengagement of the hook and the angle 4 on the bottom of the door.

The hook and the plate may be flanged to provide great strength and relative lightness in weight as shown in the several figures, although, of course, this is not absolutely necessary.

From the foregoing it will be seen that I have provided a locking device which is exceedingly simple in construction, compact in nature, relatively strong and easy to opcrate. Due to the eccentric mounting of the hook, the door may be supported in a temporary position and by the use of a wrench sufficient force may be exerted to swing the hook to its final position which will raise the door and securely lock the same in its closed position.

Many slight changes may be made without in any way departing from the spirit and scope of the invention.

What I claim as new and desire to secure by Letters Patent is 1.
